S&S CYCLE Easy Start Cam Kit - Twin Cam 106-4840

Cold starts on high-compression big-twins demand serious starter demand and battery drain—the S&S Easy Start Cam Kit eliminates this struggle by reducing initial crank compression until ignition, then automatically engaging full power once running. You'll extend starter and battery life dramatically while gaining the reliability to fire your engine regardless of displacement or compression ratio. Best of all, there's zero performance penalty once the engine runs; the compression release retracts centrifugally, delivering stock power delivery with none of the compromise.
